Eclipse 3.5 RC? SDK Build Id: I20090522-1710 JDT Build id: I20090515-1143 Got a deadlock trying to open the outline pop-up (Ctrl-O) for a class.

Looks like everyone's waiting in ASTProvider.java:456. Rafael, how do you know it's a deadlock and not just slowness that would eventually resolve itself?
Looks like bug 266510.
> Looks like bug 266510. Yep. Rafael, do you remember what file you were editing and when this happened (right after startup / during or after a build / after a crash / while doing a search / ...)?
Markus, it was just intuition. The UI froze for several minutes, the machine didn't seem busy, and the threads shown below didn't seem to be doing any actual work (but I guess if this is a duplicate of bug 266510 you are saying some of them are?). Sorry, don't remember the details of when it happened.
